DETROIT — US Representative Mike Rogers of Michigan, who has taken on an increasingly sharp profile in Washington as chairman of the House Intelligence Committee in a time of widening global security crises, has decided to give up his seat in Congress for a career in broadcasting.

Rogers, a seven-term Republican lawmaker and former FBI agent, said in an interview Friday that he will not seek re-election after his term ends this year.

Instead, Rogers told Detroit radio station WJR-AM that he will launch a radio show on stations affiliated with Atlanta-based Cumulus Media.

“As I close this chapter in my life, I am excited to begin a new one that allows me to continue serving as a voice for American exceptionalism and support a strong national security policy agenda,” Rogers said in a statement.

The 50-year-old established an impressive broadcast resume with regular appearances on nationally broadcast Sunday interview shows.

As international issues, incidents, and crises mounted in trouble spots ranging from North Korea and Iran to Syria and now Russia, Ukraine, and the Crimean Peninsula, his presence on the airwaves has been increasing.

Rogers’s face became even more familiar in recent months amid the burgeoning controversy over widespread telephone surveillance by the National Security Agency.

On that issue, Rogers took the middle road, saying he shared concerns about individual privacy but also understood the need for an increasing intelligence capacity in a time of persistent threats of terrorist attack.

In recent months, he has worked closely with Democrats on intelligence issues, an unusual display of bipartisanship in a divided Congress.
